Default: There is no default


The SCN that most closely matches the specified time is found, and this SCN is used to enable the Flashback utility. The export operation is performed with data that is consistent up to this SCN.

Syntax and Description


Because the TO_TIMESTAMP value is enclosed in quotation marks, it would be best to put this parameter in a parameter file. See "Use of Quotation Marks On the Data Pump Command Line".


  • FLASHBACK_TIME and FLASHBACK_SCN are mutually exclusive.

  • The FLASHBACK_TIME parameter pertains only to the flashback query capability of Oracle Database. It is not applicable to Flashback Database, Flashback Drop, or Flashback Data Archive.


You can specify the time in any format that the DBMS_FLASHBACK.ENABLE_AT_TIME procedure accepts. For example, suppose you have a parameter file, flashback.par, with the following contents:

FLASHBACK_TIME="TO_TIMESTAMP('27-10-2012 13:16:00', 'DD-MM-YYYY HH24:MI:SS')"

You could then issue the following command:

> expdp hr PARFILE=flashback.par

The export operation will be performed with data that is consistent with the SCN that most closely matches the specified time.


If you are on a logical standby system and using a network link to access the logical standby primary, then the FLASHBACK_SCN parameter is ignored because SCNs are selected by logical standby. See Oracle Data Guard Concepts and Administration for information about logical standby databases.
